Overview
BVOH (Butenediol vinyl alcohol copolymer) is a water-soluble thermoplastic optimized for the FFF manufacturing process. Our BVOH extends the compatibility with most of BCN3D filaments and can be easily printed to create the support and then dissolved with ordinary water.
In comparison with PVA, BVOH supports allow to achieve better surface quality, to orientate the part to get better mechanical properties and even to print multi-component models and mechanisms with a fastest dissolution and easier to remove.

Applications
- Water-soluble supports for partially enclosed cavities and complex geometries
- Smooth finish on functional prototypes
- Sacrificial molds
- Movable mechanisms
- Hollow parts
BCN3D Filaments
Industrial-grade materials manufactured by BASF and Mitsubishi Chemical and designed to deliver outstanding results for BCN3D printers.
Technical Information
Dissolution time BVOH vs PVA
BVOH is an outstanding support material for dual extrusion with record dissolution times in water compared with PVA. During the solubility test, BVOH shows dissolution times in water two times faster than PVA.

Get a proper printing profile for BVOH using the ones integrated into the BCN3D Stratos.
Bed adhesion:
To ensure good bed adhesion use Magigoo.
Recommendations:
- Store it in an airtight container with desiccant.
- Dry filament before printing. Place it in a hot air dryer or vacuum oven at 60ºC for 4 to 16 hours.
- Calibrate the printer to ensure a reliable adhesion between materials and a proper alignment of both printheads.
- Clean the hotend after long prints or when switching material.

Printing of large overhangs
Our BVOH is compatible with PLA, PET-G, ABS, TPU, PA and PAHT CF15, thus allowing the creation of water-soluble support structures for the printing of parts also when using highly technical materials.
Printing of complex parts
Exceptional quality of the surfaces in contact with the supports and easy removal of the support even in hard-to-reach geometries.
Support for technical materials
Excellent compatibility and adhesion with ABS and exceptional quality of the surface in contact with the support material.
